RELATED FIELD

A vehicle monitoring system and methods of use are provided. In some embodiments, a convex rear-view mirror and modular monitor system for enhanced viewing by a vehicle operator of areas within and/or exterior to a vehicle, and methods of using the system, are provided. In some embodiments, the convex rear-view mirror and modular monitor system is configured for use on a bus, school bus and/or public transit vehicle.

BACKGROUND

Existing vehicle monitoring systems capture still images and/or video images, and display the images on a monitor for the vehicle operator to view. For example, many large vehicles are equipped with a back-up camera and a monitor to assist the vehicle operator in moving the vehicle in reverse. However, such monitors can be a cause of excessive distraction for the vehicle operator, depending on their location.

In addition, many monitoring systems are installed such that, due to the configuration of the parts, and the method of installation, should an integral part like the monitor malfunction, accessing, fixing and/or replacing the integral part is often cumbersome and expensive.

SUMMARY

Accordingly, a convex rear-view mirror and modular monitor system is provided that includes an interior mirror having a reversible ball and socket mechanism mount that in some embodiments embeds a modular monitor behind, for example, see-through mirror glass. In some embodiments, the rear view mirror comprises a convex surface and the monitor is attached to the rear-view mirror system with a sloping configuration. In some embodiments, the monitor is placed in the middle of the rear view mirror with a support plate configuration. In some embodiments, the system includes multiple cameras, some in the vehicle, bus, school bus, public transit vehicle and/or truck, as well as some cameras outside the vehicle, bus, school bus, public transit vehicle and/or truck, advantageously providing the driver, other individual and/or other vehicle passenger an opportunity to view what is happening, for example, in the back rows of the bus and/or cabin, while also using the mirror to look at objects in the bus and/or cabin that are visible using the mirror.

Embodiments of the convex rear-view mirror and modular monitor system enable the maximizing of safe usage by automating when the modular monitor will display images, and when the driver will have full view of the rear-view mirror. For example, one type of automation is time based, wherein a certain intervals images are displayed (e.g., during hours when it is known that children will be on-board a bus). Another type of automation is event-based, wherein an image may be displayed when the door of vehicle is opened, when red flashers are activated, and/or when the stop arm is activated. Images from a rear-view camera may be displayed in some embodiments only when the vehicle is placed in reverse. In some embodiments, two or more of the above automated viewing features may be used in combination.

In some embodiments the system comprises manual input selection, for use in certain situations. For example, when a driver cannot see activity happening behind high seat backs or otherwise outside the view of the driver, even with a rear-view mirror, a driver may choose to view such activity without having to stop the vehicle or adjust the rear-view mirror.

In some embodiments, audio may be provided to the vehicle operator in coordination with video being displayed. For example, a driver may have a need to hear audio from an area inside or outside the vehicle. Embodiments of the system therefore provide microphones at or near locations where cameras are capturing images, and the audio can be provided to the driver along with the images, by way of a speaker, headset, or the like. Such microphones may be built in to the cameras, or stand-alone devices.

Additionally, in some embodiments, the rear-view mirror and modular monitor system is configured to be easily assembled and/or disassembled when necessary. The rear-view mirror and modular monitor system is provided wherein parts can be attached and/or detached and parts can be replaced easily, as necessary.

A multi-camera, rear-view mirror and modular monitor system includes a convex rear-view mirror that in some embodiments embeds a monitor behind, for example, see-through convex mirror glass. In some embodiments, the convex rear-view mirror and modular monitor system includes multiple cameras, some in the vehicle (e.g., a bus or truck, which are collectively referred to as a “bus”), as well as some cameras outside the bus, advantageously providing the driver or other individual an opportunity to view what is happening, for example, in the back rows of the bus and/or cabin, while also using the mirror to look at objects in the bus and/or cabin, and/or behind the bus, that are visible using the mirror. In some embodiments, a standard 6×30 mirror or other mirror sized for use in a bus substantially of the size of a standard 6×30 mirror, such as 5-10% smaller or 5-10% larger is advantageously used in the bus to view, for example, children that are behind the driver. In some embodiments, other mirror sizes may be used having a size configured for use in a bus, for example, 10-20% larger or smaller, that the standard 6×30 mirror. In some embodiments, this standard 6×30 mirror is not needed for viewing traffic behind the bus, and in some embodiments it may be used to view objects other than vehicles both inside and outside the bus. In some embodiments other standard and/or custom sized rear-view mirrors may also be used.

In some embodiments, a pad or support plate is disposed between the mirror opening/glass and the monitor to minimize the bleed of light and minimize light loss and/or provide support. In some embodiments, the monitor is sloped to contour of the convex glass for a more secure, close and/or tight fit. In some embodiments, the monitor is sloped to the plane tangent to the point substantially at the center of the dome that is parallel to the surface of the monitor. In some embodiments, the monitor is disposed off center, and the monitor is sloped by the sloping posts of the housing substantially conforming to the area of the convex glass, resulting in an angle between the monitor and the convex glass. In some embodiments, the monitor is secured to the rear-view mirror system and tangent to a plane that represents a projection of the center of the display to the opening of the convex glass. In some embodiments, the monitor is secured to or against a flat housing with a convex glass having a contour with a foam gasket or support plate that is sized or configured to substantially match the perimeter of the monitor, to provide support and/or minimize light loss.

In some embodiments, a standard convex rear-view mirror is used in combination with the dual-vision camera inventions described in U.S. application Ser. No. 12/608,600, filed Oct. 29, 2009, entitled “Method and System With Multiple Camera Units Installed in Protective Enclosure,” which claims priority to U.S. Application Ser. Nos. 61/109,763, filed Oct. 30, 2008 and 61/245,080, filed Sep. 23, 2009, and each of the above applications are incorporated herein by reference in their entirety. In addition or alternatively, in some embodiments, any other suitable image capturing system is also contemplated for use either in conjunction with, or instead of, the dual-vision system. For example, any digital imaging device such as a digital camera and/or a digital video recorder may be used.

Advantageously, multiple cameras are provided in, for example, a bus or other truck or vehicle as well as some cameras outside the bus, providing the driver an opportunity to see what is happening in areas in and/or around the bus that cannot be seen in the rear-view mirror, while also using the rear-view mirror to look at passengers and objects that are visible through the mirror. In addition, in some embodiments, a monitor is either embedded behind see-through mirror glass, embedded in a cut-out aperture within the rear-view mirror, and/or otherwise attached to a portion of the rear-view mirror. In any event, the driver can view both the monitor and the rear-view mirror with relative ease and limited distraction to the driver.

In some embodiments, the interior cameras are located in the rear area of the cabin of the bus and face forward in the bus to show the driver what is happening behind the high-backs of the seats which cannot be seen when looking up at a conventional mirror. Alternatively or additionally, in some embodiments, cameras may be mounted in any suitable location to capture images which would otherwise be unviewable from the rear-view mirror. This may include ceiling mounted cameras, side wall mounted cameras, rear facing cameras, and the like.

In some embodiments, external cameras may be located anywhere around the outside of the bus that would provide views which can be helpful to the driver. As an example, the present assignee describes an exterior camera system layout and driver controls which affords a view substantially 360° around a school bus in U.S. patent application Ser. No. 13/177,302, entitled: “CAMERA SYSTEM FOR LARGE VEHICLES,” filed Jul. 6, 2011, which is herein incorporated by reference in its entirety. The rear-view mirror and modular monitor system can advantageously display at least one selected imaging feed, and/or multiple imaging feeds simultaneously using standard monitor technology and/or multiple monitor modules connected to the rear view mirror. Additionally, corresponding audio for an area inside or external to the bus being displayed on the modular monitor may also be provided to the driver via the rear-view mirror and modular monitor system, which, in some embodiments, incorporates microphones built into the imaging devices and/or installed in the location of the imaging devices.

FIGS. 1 a-b depict a general layout of a system for effectuating the present invention in accordance with some embodiments of the invention. In some embodiments, rear-view mirror and modular monitoring system 100 comprises, for example, at least three primary components: rear-view mirror unit 110, modular monitor 120, and imaging device 130. Modular monitor 120 and imaging device 130 are shown connected to each other via connection device 140.

In some embodiments, rear-view mirror unit 110 includes mirror 111 and at least one see-through mirror glass section 112, behind which modular monitor 120 is mounted for display. In some embodiments, mirror 111 may include a mirror cut-out aperture (not shown) in place of, or in addition to, see-through mirror glass section 112, behind which modular monitor 120 may be mounted for display. In yet other embodiments, modular monitor 120 may be mounted to any suitable portion of rear-view mirror unit 110 that provides sufficient viewing of modular monitor 120 and mirror 111.

In some embodiments, mirror 111 is a sheet of glass coated on the back side with black and chrome paint, making the front side reflective, similar to any standard rear-view mirror. As described herein, in some embodiments, a see-through mirror glass section 112 may refer to a section of mirror 111 where the glass is coated with chrome paint only, or otherwise treated so as to make a standard see-through glass section 112 sufficiently transparent (when viewed from the front) when a strong enough light source, such as the light from an activated monitor display, is channeled through the back of the section, and is otherwise reflective (when viewed from the front side) when the light source is not provided or otherwise insufficient.

In some embodiments, the rear-view mirror has a unitary reflecting surface of a single reflectivity or includes at least two areas of different reflectivity: a first area having a relatively low reflectivity, and a second area, such as the remaining area of the reflecting surface, having a higher reflectivity. For example, as illustrated in FIG. 14 a , the first area 1411 can be on one side of a mirror 1410, and the second area 1412 can be the remaining area on the mirror 1410. In alternative embodiments, the first area can be located in the other positions within the mirror 1400, for example, in the middle of the mirror (1411′). As the first area is intended to cover an LCD monitor installed behind it, the placement and the size of the first area can be based on the size of the monitor screen and the monitor placement. More than one area of low reflectivity can be included as desired (e.g., if more than one monitor is used). The area of the higher reflectivity should be sufficiently large to ensure adequate reflectivity of the overall mirror. For example, the area of lower reflectivity can be about ⅙ to about ⅓ of the whole mirror area.

Such embodiments address an important problem for the design of an interior mirror which is intended to view the details of occupants of a vehicle, e.g., a school bus, where the interior mirror is used mainly to see details of, for example, students and/or children. As the interior of the school bus usually only has limited lighting, we have determined that it is desirable that the mirror has sufficient reflectivity. (By contrast, a standard interior mirror of passenger cars does not need to be as reflective because the mirror is used to see cars behind the vehicle which are visible either by their clearly defined daytime image or by their headlights at night.) However, when the mirror is used in conjunction with an LCD monitor as described in one or more embodiments of the present invention, the reflectivity should not be too high such that it would be difficult for the driver to see the images on the LCD monitor because of the glare on the mirror caused by the light from the surrounding environment (e.g., sunlight). In general, if the overall reflectivity of the mirror is, for example, in the 50-60% range, the whole mirror will be bright but not transmissive; when the reflectivity is, for example, below 20% (such as glass without a reflective, tinted or other type of coating, which has a reflectance of, for example, about 4% depending on the type of glass), the mirror is transmissive, and thus reflective images may appear too dark. A preferred reflectivity level for the mirror with single reflectivity (e.g., the reflectivity of the mirror in zone 1412 is substantially the same as that in zones 1411 and 1411′ and the zone being within 5% reflectivity of each other or the zones being similar to each other and within 10% reflectivity of each other) would be between about 20% and 40%, alternatively between about 25% and 35%, more preferably and/or alternatively still about 30% (e.g., about a percentage reflects a 5% or less differential in reflectivity for a specific reflectivity value), so the mirror is sufficiently bright for a school bus with low interior lighting but transmissive enough to see the images of the LCD behind the glass. A mirror having a uniform low reflectivity is shown in FIG. 15 a (when the monitor is off) and FIG. 15 b (when the monitor is on). Although the low reflectivity helps the LCD screen of the monitor shine through the mirror, we have determined that the images in the mirror can be too dark for the driver to see the details inside of the bus. Nonetheless, in some embodiments, an additional tint may optionally be applied to either or both areas of the mirror. This tint may be provided to reduce unwanted glare, such as from solar reflection, headlights or the like. In some embodiments, the mirror may be tinted towards a specific color, such as yellow, by selectively preventing reflectance of unwanted wavelengths, such as blues and violets, so as to improve overall visibility. Tinting may also be provided to globally reduce the reflectance of all visible wavelengths by a predetermined amount, such as from 5% to 50%. Combinations may also be provided, so as to both reduce the reflectance of all wavelengths by a predetermined amount, such as 10% to 30%, while further suppressing, or even eliminating, the reflectance of other wavelengths, such as blues and violets. Any suitable optical filter or thin film may be used to provide such tinting.

In some embodiments with areas having different reflectivity, the higher reflectivity area can be made sufficiently high to ensure adequate light is reflected from the mirror to allow clear view of the target viewing area of the mirror, especially for low-light settings, such as the interior of a bus later in the day, or the like. Meanwhile, the reflectivity of the lower reflectivity area can be selected such that it has sufficient transmittance to allow the images on the monitor (when the monitor is on) to transmit through the mirror and overwhelm any glare coming from the sunlight or other light from outside and/or inside the bus so as to be viewable by the observer (e.g., a bus driver) under such lighting conditions. In some embodiments, multiple and/or any number of reflective areas may be used in different areas of the mirror to provide sufficient reflective properties for viewing inside and/or outside the vehicle while allowing the monitor to be adequately viewed when in operation. In this regard, in some embodiments. it is preferable to use a monitor that has high LCD brightness.

In some embodiments, the monitor can have an LCD screen whose brightness can be manually adjusted, and/or automatically adjusted depending on the ambient light and/or glare coming from other light sources. As illustrated in FIG. 14 b , in some embodiments, the monitor module 1430 includes at least an LCD screen 1432, a control module 1435, and a light sensor 1437. The light sensor (e.g., a photocell) can be mounted proximate the LCD screen and behind the first area of the mirror having low reflectivity, or mounted on the frame of the mirror, or other locations as preferred or desired. The light sensor 1437 can sense, for example, the ambient light level and generate a corresponding electric signal, and transmit the electric signal to the control module 1435, which can include a control circuit so that the signal received from the light sensor 1437 can be processed to generate a control signal to automatically adjust the brightness of the LCD screen 1432, such as by controlling the brightness of a backlight of the LCD screen 1432. In some embodiments, different brightness settings may be used and/or user selectable to allow automatic brightness control responsive to predefined user and/or monitor settings. In alternative embodiments, in addition to or instead of the automated control module 1435, a manual brightness switch is used to control the monitor brightness.

With reference to FIG. 16 . to manufacture the mirror having the two areas of reflectivity, in some embodiments, the below exemplary process 400 can be used: (step 402) applying one or more reflective coatings of a first reflective material on the entirety of the mirror surface of a mirror substrate; (step 404) masking the first area where the low reflectivity is desired, and (step 406) applying a further coating of either the same reflective material, or a second, different reflective material to the area outside of the masked first area. Alternative methods can be used, for example, by applying a first reflective coating only on the first area and a second reflective coating only in the remaining area. Commonly known metal-based reflective materials and/or paints can be used, for example, chrome-based coating or paint. Multiple layers of coatings can be applied to the first area and/or the remaining mirror area as needed to obtain the desired reflectivity. In some embodiments, (step 408) the mask may be removed after one or more of the desired reflective coatings have been applied, and in particular after the final reflective coating in step 406 has been applied. In some embodiments, an opaque coating, such as black paint, may be applied before removal of the mask and thereafter the mask is optionally removed so that the first area is devoid of the opaque coating.

In some embodiments, the second area (having a higher reflectivity) can have a reflectivity in the 50-60% range, while the first area of relatively low reflectivity can have a reflectivity of 25% to 35%, or alternatively of about 20% or lower. Embodiments with a 20% reflectivity area are illustrated in FIG. 15 c (when the monitor is turned off) and FIG. 15 d (when the monitor is on). However, in such embodiments, because of the high contrast of reflectivity between the two areas, the difference between the two areas can be visible when the monitor is off, as shown in FIG. 15 c , (where the first area is visible as a darker area embedded in a brighter area). This can cause discomfort or annoyance to the driver. In preferred embodiments, the reflectivity of the first area and the second area can be selected such that the difference in reflectivity between the first area and the other parts of the mirror is not visible or perceivable under normal operating conditions (when the monitor is off), as shown in FIG. 15 e (FIG. 15 f shows such a mirror when the monitor is turned on). For example, the reflectivity of the first area 1411 can be selected to be about two-thirds of the reflectivity of the higher reflectivity area 1412 (e.g., the remaining mirror area), e.g., the reflectivity of the first area 1411 can be selected to be about 30%, and the reflectivity of the second area 1412 can be selected to be about 45%. High brightness LCD monitors can be particularly useful in such embodiments to overcome the not-too-low reflectivity of the first area 1411, e.g., those have or can be adjusted to have a brightness of 1,000-1,2000 candelas per square meter. Other values of reflectivity in the two areas (and/or the contrast ratio of the reflectivity between the two areas) can be selected based on different applications, parts of the country, positions of the mirror within the bus, etc. In yet other embodiments, the reflectivity of both the first area 1411 and the second area 1412 can be substantially the same or similar to each other, such as between 20% and 40%, between 25% and 35%, and/or around 25% or 30%. Masking may or may not be employed is such embodiments. In some embodiments, second area 1412 may have an opaque backing while first area 1411 does not.

In some embodiments, as shown in FIG. 14 a , a transition region 1413 may be disposed between the first area 1411 and the second area 1412, in which the transition region 1413 has an intermediate reflectivity that is between the respective reflectivities of the first area 1411 and the second area 1412. In preferred embodiments, the transition region 1413 has a plurality of successively increasing reflectivities from the first area 1411 to the second area 1412, so that the reflectivity of the mirror 1410 steadily increases in stepwise fashion from the first area 1411 to the second area 1412 within the transition region 1413. It will be appreciated that, with a suitable number of steps and/or application of reflective material, the reflectivity of the transition region 1413 can be made to appear to smoothly increase from a minimum value that is substantially the same as the reflectivity of the first area 1411, and which abuts the first area 1411, to a maximum value that is substantially the same as the reflectivity of the second area 1412 and which abuts the second area 1412. In one specific embodiment, the first reflectivity of the first area 1411 and second reflectivity of the second area 1412 are substantially similar to each other (e.g., within 5-10% of each other), and the reflectivity of the transition region 1413 serves to provide a smooth or stepped blending between the first and second reflectivities. In some embodiments, multiple reflective areas (e.g., more than two) may be used in different areas of the mirror to provide sufficient reflective properties for viewing inside and/or outside the vehicle while allowing the monitor to be adequately viewed when in operation.

In some embodiments, and referring back to FIGS. 1 a and 1 b , rear-view mirror unit 110 includes mirror unit mounting brackets 113. The configuration of mirror unit mounting brackets 113 is merely exemplary, and any suitable configuration which provides proper mounting support for rear-view mirror unit 110 in a vehicle is likewise contemplated. Additionally or alternatively, in some embodiments, rear-view mirror unit 110 may be provided with a standard locking mechanism, as described in further detail in the description of FIG. 7 , to lock rear-view mirror unit 110 in place.

In some embodiments, image capture device 130 is a standard digital still and/or video camera. In some embodiments, image capture device 130 also includes Infrared (IR) Light Emitting Diode (LED) lighting (or equivalent IR lighting) for capturing images in low or no visibility without requiring a flash or other bright light source. In some embodiments, a standard light source may be provided in addition to or in place of IR LED lighting. While image capture device 130 is shown here with a wired connection to modular monitor 120, in some embodiments image capture device 130 may be a wireless device, which is controlled and transmits captured images wirelessly via a wireless transmission such as Wi-Fi, Bluetooth, IR, cellular etc. Furthermore, while image capture device 130 is shown here as a stationary camera, in some embodiments image capture device 130 may be a standard motorized, multi-directional manually/automatically controlled camera, which may provide the operator with additional views inside and/or outside the bus. In some embodiments, image capture device 130 is powered by at least one of the vehicle's internal power source, and a stand-alone power source such as a rechargeable camera battery or a solar cell.

In some embodiments, connection device 140 comprises one or a plurality of input feeds 141. In some embodiments, the input feeds 141 are standard video input feeds, which can be connected to any number and combination of devices. For example, input feeds 141 may be respectively connected to multiple image capture devices 130 and/or a combination of image capture devices 130, audio capture devices (not shown), e.g., a microphone, and/or other sensors, e.g., a photocell light sensor, as desired. In some embodiments, connection device 140 further comprises a power feed 142 for providing power to modular monitor 120 from a power source (not shown), e.g., the vehicle battery, and a line out feed 143, for connecting modular monitor 120 to an output device such as, for example, a stand-alone speaker (not shown) or additional monitor (not shown).

In some embodiments, connection device 140 includes monitor video feed 144, to provide at least one a digital image, an audio signal, sensor data, and power to the monitor 120, and to provide output from the modular monitor 120 to an output device. It will be readily understood by those of ordinary skill in the art that, while in the embodiments described herein, connection device 140 is shown as one comprehensive configuration, other embodiments providing for multiple separate standard connection devices and/or other configurations employing standard connection devices and/or wireless connections may also be used.

FIGS. 2 a-d depict several views of a rear-view mirror and modular monitor assembly in accordance with some embodiments of the invention. In particular FIG. 2 a depicts a front view of rear-view mirror unit 110 and see-through mirror glass section 112, the exemplary location of which is depicted by a hash-lined rectangle. It will again be readily understood by those of ordinary skill in the art that, while in the embodiments described herein, see-through mirror glass section 112 is depicted as being rectangular in shape, any other shape suitable for commensurate with the shape of a monitor display to be attached thereto is also contemplated. Additionally, as explained above, while the hash-lined rectangle is described as indicating the general location of see-through mirror glass section 112, in some embodiments, the hash-lined rectangle indicates the general location of a mirror cut-out aperture (not shown) in place of, or in addition to, see-through mirror glass section 112, behind which modular monitor 120 may be mounted for display. In yet other embodiments, modular monitor 120 may be mounted to any suitable portion of rear-view mirror unit 110 that provides sufficient viewing of modular monitor 120 and mirror 111, without necessitating see-through mirror glass section 112 or a mirror cut-out aperture. In yet other embodiments, the rear-view mirror may include an additional section, slot or receptacle, optionally molded, within and/or integrated with the housing to accommodate the monitor for connection and facilitate easy removal therefrom.

FIG. 2 b depicts a back view of the exemplary rear-view mirror unit 110 of FIG. 2 a , with modular monitor 120 fastened to the back, adjacent to the reverse (back) side of the location of see-through mirror glass section 112. It will again be readily understood by those of ordinary skill in the art that, while in the embodiments described herein, see-through mirror glass section 112 and modular monitor 120 are shown located to one side of rear-view mirror unit 110, this is merely exemplary, and other locations along mirror 111 are also contemplated. In addition to depicting mirror unit mounting brackets 113, FIG. 2 b also depicts fixed mounting bracket 114, which is discussed in greater detail in the description of FIG. 7 below. Other embodiments include fewer or more brackets, and other configurations as necessary to secure rear-view mirror unit 110 in place. It should also be noted that, while the embodiments described herein depict rear-view mirror unit 110 as being fastened to an internal portion of a vehicle, alternative embodiments wherein rear-view mirror unit 110 is mounting to an external portion of a vehicle are also provided.

FIGS. 2 c-d depict several alternative views of rear-view mirror unit 110 and modular monitor 120 in accordance with some embodiments.

FIG. 3 depicts an exploded view of a rear-view mirror and modular monitor assembly in accordance with some embodiments of the invention. In particular, FIG. 3 shows how modular monitor 120 may be fastened to rear-view mirror unit 110, and how rear-view mirror unit 110 may be assembled, in accordance with some embodiments of the invention.

In accordance with some embodiments, modular monitor 120 may be fastened to rear-view mirror unit 110 with the use of self-clinching threaded pin fasteners, such as monitor fasteners 118, and monitor nuts 119 for securing monitor fasteners 118 in place. Other types of fasteners may alternatively be used as well, such as screws, adhesives, snap fit, adhesive tape, velcro and the like. In some embodiments, modular monitor 120 may be fastened directly to mirror unit backing 116 by threading monitor fasteners 118 through mirror unit backing apertures 165 located around the perimeter of backing cut-out 172, and through modular monitor apertures 127, which are located along the perimeter of monitor frame 126, and securing monitor fasteners 118 in place with monitor nuts 119.

However, in other embodiments, modular monitor 120 is fastened to mirror unit backing 116 with monitor gasket 117 disposed therebetween. Monitor gasket 117 optionally includes gasket apertures 129. In some embodiments, monitor fasteners 118 are threaded first through mirror unit backing apertures 165, then through gasket apertures 129, and finally through modular monitor apertures 127, after which they are secured with monitor nuts 119.

In some embodiments, monitor gasket 117 advantageously serves to block external light from disturbing an image displayed on modular monitor 120 by reaching monitor display 121 from between modular monitor 120 and the reverse side of see-through mirror glass section 112. Monitor gasket 117 also serves to channel the light (image) emitted by monitor display 121 through the reverse side of see-through mirror glass section 112, as well as to protect monitor display 121 from any incidental rubbing or scratching against mirror unit backing 116. In some embodiments, monitor gasket 117 is configured and shaped to follow the perimeter of monitor display 121.

As shown in FIG. 3 , in some embodiments, rear-view mirror unit 110 is further assembled by inserting mirror 111 into mirror unit backing 116 and affixing mirror 111 in place using mirror frame 115. In some embodiments, mirror frame 115 is fastened to mirror unit backing 116 by way of additional fasteners. In other embodiments, mirror frame 115 is shaped and configured so as to become affixed to mirror unite backing 116 when a sufficient force is applied to mirror frame 115, so that at least a portion of mirror frame 115 is held in place over mirror unit backing 116, such as, for example, by employing the use of a lip, indentation, or groove (not shown) to which mirror frame 115 can attach. Other methods of attachment are of course also contemplated, such by use of an adhesive or bond. Additionally, the back of mirror 111 and/or the internal surface of backing 116, may be coated with a pressure-sensitive adhesive or the like to better couple mirror 111 to backing 116. In certain embodiments, the pressure sensitive tape or adhesive that is added to the back of the mirror glass 111 is selected to make the glass shatter-proof or shatter-resistant.

In some embodiments, assembly of rear-view mirror unit 110 may be completed by affixing fixed mounting bracket 114 to mirror unit backing 116. In some embodiments, fixed mounting bracket 114 is connected to L-brackets 152 and 153 using fastener 166, washers 167, and nuts 168. L-brackets 152 and 153 are connected to mirror unit backing 116, for example, by inserting fasteners 169 through L-bracket apertures 170 and affixing them to backing bracket apertures 171.

While the above description of FIG. 3 provides an example embodiment of an assembly of rear-view mirror unit 110 and modular monitor 120, those of ordinary skill in the art will readily recognize that many features of the above descriptions are exemplary in nature. For example, in place of a fastener, an adhesive or bond might be employed.

FIGS. 4 a-e depict several views of a modular monitor in accordance with some embodiments of the invention. FIG. 4 a depicts a front view of modular monitor 120 in accordance with some embodiments. As can be seen in FIG. 4 a , modular monitor 120 includes monitor display 121 on a front face of the monitor. In some embodiments monitor display 121 is an LCD monitor. However, other display types are also contemplated, such as LED monitors, OLED monitors, etc. In some embodiments, monitor display 121 provides strong enough light levels so that images displayed on monitor display 121 will be clearly visible through see-through mirror glass section 112. In alternative embodiments when a mirror cut-out aperture is used in place of see-through mirror glass section 112, a relatively weaker display may be sufficient for proper visibility of the images.

FIG. 4 b depicts a back view of modular monitor 120 in accordance with some embodiments. As can be seen in FIG. 4 b , modular monitor 120 includes monitor speakers 122 on a rear face of the monitor. Of course, in other embodiments, monitor speakers 122 may be located on another side of modular monitor 120. In yet other embodiments, no speakers are integrated into modular monitor 120, as can be seen, for example, in FIG. 2 d . In some embodiments, an output port is provided in addition to, or in place of, monitor speakers 122, to provide audio output to external audio devices such as an external speaker, wired headsets, and/or wireless headsets.

In some embodiments, manual controls 123 are provided on modular monitor 120. In some embodiments, manual controls 123 control power, volume, input selection, settings for automatic use, and/or other settings. In some embodiments, modular monitor 120 includes sensor 124 and indicator light 125. In some embodiments, sensor 124 may be a photocell light sensor, which detects levels of ambient light in the area around modular monitor 120, and can adjust the brightness of monitor display 121 to compensate for excess and/or insufficient light. Indicator light 125 may be configured to indicate, for example, that modular monitor 120 is powered on or off, and/or operating correctly.

In some embodiments, modular monitor 120 may have built-in and/or removable memory (not shown) for recording images and/or audio.

FIGS. 4 c-e depict additional views of modular monitor 120 in accordance with the invention.

FIGS. 5 a-d depict several views of an example image capture device 130 in accordance with some embodiments of the invention. As explained above, in some embodiments, image capture device 130 may be for example, a standard digital still and/or video camera, an IR/LED camera or the like. Additionally, in some embodiments, image capture device 130 may further comprise a built-in audio capture device (microphone). Furthermore, though image capture device 130 is shown with a wired connection device, a partially or completely wireless image capture device is also contemplated. Likewise, in some embodiments, image capture device 130 may be powered by the vehicle, and/or may have an internal battery.

FIGS. 6 a-d depict several views of a vehicle with a rear-view mirror and modular monitor system installed in accordance with some embodiments of the invention. In some embodiments, as illustrated in FIG. 6 a seen from behind the driver, when the bus is in reverse, monitor display 121 can be configured to always show camera 3 view (back-up) as shown in FIG. 6 d . When not in reverse, the driver can then manually choose video inputs from cameras 1, 2, or 3 (exemplary locations of which are depicted in FIG. 6 d ) from video input switch 180 by way of respective switches 181, 182, 183, or choose no view at all (full mirror view).

In alternative embodiments, as illustrated in FIG. 6 b seen from behind the driver, when the vehicle is in reverse, monitor display 121 can be configured to always show camera 3 view (back-up). When not in reverse, the driver can use video input switch 180, located on dashboard 185, to choose a single-feed configuration providing a video input from either camera 1 or camera 2, a multiple-feed configuration providing a split video input of cameras 1 and 2, input from camera 3, or no view at all (full mirror view).

In additional alternative embodiments, the selection of the view for the monitors can be based on driver preference using a standard input switch mechanism, manually or manually activated. For example, when not in reverse mode, the driver might still want camera 3 providing input to the monitor as part of the multiple-feed split video configuration.

FIG. 6 c depicts a view from above of an exemplary location of rear-view mirror unit 110 and video input switch 180 relative to the driver. FIG. 6 d provides exemplary mounting locations for cameras within and external to the bus.

In some embodiments, the video switch 180 or other existing or additional switch can be configured to select one or more video feeds from one or more cameras based upon one or more optional triggering signals. In some embodiments, a first triggering signal comprises a backup signal that indicates that the vehicle has been placed in reverse and/or is ready to move in reverse. Any suitable method may be used to obtain such a signal, such as by using the backup lights, a signal from the transmission, drive selector moved to reverse, or the like. A second optional triggering signal comprises a stop-completed signal, indicating that the vehicle has completed a stop and is preparing to move forward in continuance of its journey. Any specific method may be used to obtain such a signal. With specific reference to busses, the stop completed signal can be obtained, for example, from monitoring when the door has been closed; that is, the closing of the passenger door can be interpreted as a stop completed signal, which can be used by the video switch 180. In a school bus, for example, the stop completed signal can be optionally obtained by monitoring the flashing lights that are displayed when a school bus has stopped and/or other shifting of the bus into forward or reverse gear, and the like. In some embodiments, when the flashing lights cease flashing (e.g., are turned off) or the gears have changed or moved from parked to forward or reverse, this event can be interpreted as a stop completed signal.

In busses, and for school busses in particular, it is very desirable to have an external view of one or more the sides of the bus as the vehicle pulls away from a stop, as individuals that are in close proximity to a bus when the vehicle pulls away may be inadvertently struck by the vehicle. To provide a driver with ample opportunity to review the sides of or around the bus for hazard conditions, in one embodiment the video input switch 180 is configured to monitor the stop completed signal and to selected a video feed from an external camera for display in monitor display 121 for a predetermined amount of time after receiving the stop completed signal, such as for 5 to 15 seconds, more preferably about 10 seconds. In some embodiments, the selected video feed is from one or more cameras that monitors a side(s), front or rear of the bus. For example, with reference to FIG. 6 d , upon receiving the stop completed signal, such as when the bus doors close and/or the flashing warning lights are turned off, the video switch 180 selects a video feed from camera 2 and causes this feed to be presented on display 121 for 10 seconds; alternatively, a split-view scene could be presented in display 121 formed by the video splitter 180 by a combination of the video feeds from both cameras 1 and 2 so that both the left and right sides of the bus are presented in a single view 121.

Although backup cameras are highly desirable when backing up a vehicle, in some situations their use may be discouraged in favor of side view and/or rear view mirrors. Hence, in some embodiments, upon receiving the backup signal, the video switch 180 may temporarily disable the video feed for the backup camera 3 for a predetermined amount of time, such as 30 seconds to two minutes, more preferably for about one minute, and instead require the driver to use the external mirrors instead of relying on a monitor in the interior of the bus. After this predetermined amount of time has elapsed the video, switch 180 may then cause the video feed from the backup camera 3 to be presented in the display 121, assuming that the bus is still in reverse as indicated by the backup signal or if such as display is manually requested, such as by a switch 183.

FIG. 7 depicts an optional lever lock mechanism which can be used to lock a rear-view mirror and modular monitor assembly in place in accordance with some embodiments of the invention.

It will be understood that, while particular components of locking mechanism 150 are described herein, various parts may be omitted, or may be combined and formed integrally, or the parts may be arranged in different ways without departing from the spirit of the present disclosure. For example, while helical compression spring 154 is described, it will be appreciated that other types of springs or non-spring urging members may be used to apply pressure to L-bracket 152 as described below; or, while mounting bracket 114 is described as being attached to the bus, other types of fasteners may be used to secure rear-view mirror unit 110 or locking mechanism 150 to the vehicle.

FIGS. 8 a-b depict several views of a dual-vision camera system which may be used in conjunction with a rear-view mirror and modular monitor system in accordance with some embodiments of the invention.

In some embodiments, a dual-vision camera system can be used in place of, or in conjunction with image capture device 130 to provide images and/or audio to modular monitor 120. The illustrative camera system, disclosed in incorporated by reference U.S. patent application Ser. No. 12/608,600 cited above, records images of both the interior and exterior of a vehicle. Specifically, the camera system provides for recording the interior and exterior of a vehicle on a continuous loop, with the oldest data erased by more recent video, and will save sequences of video and audio recordings based upon certain predetermined recording events.

The dual-vision system 200 of FIGS. 8 a and 8 b includes in at least one embodiment two cameras within the same housing: one camera captures video of the interior of the vehicle, while the second camera captures video of vehicles, pedestrians, road signs, traffic lights, etc. in front of the vehicle. In alternative embodiments, the dual-vision system 200 is provided with a microphone to record audio within the interior of the vehicle. In alternative embodiments, different numbers of cameras can be used with different field of views, from a single camera to a number of different cameras. One advantage of the camera system is that it allows the recording of the video of the driver and/or passengers of the vehicle in addition to video of the outside of the vehicle to allow review of events, such as distractions to the driver within the vehicle, car accidents, near-accidents, etc.

For example, according to one embodiment, the camera system records images from both a camera pointed in the direction of travel of the vehicle as well as a camera pointed towards the interior of the vehicle. In some embodiments, the cameras capture images at regular intervals, for example, one frame every second or every other second, whereas in other embodiments, the cameras capture motion video at 15 frames per second, 24 frames per second or 30 frames per second. In alternative embodiments, the camera system stores video in a continuous loop on a memory or other standard data storage device, for example, a standard SD card. As will be understood, other types of standard memory devices such as hard drives, data storage, tape drives, etc. are contemplated by the camera system. In alternative embodiments, the memory card, e.g., SD card and the like, for the recording device is removable. The memory card may be lockable to prevent theft or tampering with the data.

Video will continue to be captured, overwriting non-protected portions of the memory until a recording event occurs such as the driver activating a panic button, a g-force measured beyond a certain threshold by an accelerometer in 3-axis, a g-force measured beyond a certain threshold by an accelerometer in 2 axis, a sufficient bump is measured by an accelerometer, excessive brake is measured by an accelerometer or other device connected to the vehicle braking system, speed exceeds a certain predetermined threshold, and the like. Audio and/or video captured in response to a recording event is stored for later review and will not be overwritten by continuous loop recording until indicated by an individual with sufficient permissions, e.g., transportation manager. Captured video and/or audio recorded in response to a recording event, in alternative embodiments, is recorded on a separate part of the memory card or alternatively a separate memory that cannot be over-written except by someone with additional permissions, e.g., transportation manager. In some embodiments, video and/or audio captured before and/or after the event is stored in a separate memory or protected area of the memory or marked as non-erasable to prevent its erasure. In some embodiments, the type of recording event, e.g., braking event, collision, etc., is stored along with the audio and/or video of the recording event to allow sorting of recordings at a later time.

In certain embodiments, the dual-vision system 200 is provided with a built-in standard GPS sensor, which can determine the location, speed and direction of the vehicle. In certain embodiments, the GPS location of the vehicle is recorded along with the audio and/or video recorded in a continuous loop. In other embodiments, the GPS location is recorded only when a recording event occurs. In alternative embodiments, the dual camera system unit 200 can optionally connect directly to the windshield or other location of the vehicle directly without the need of an additional enclosure. For example, the slots/grooves on either the front or back side can be used to connect/slide into any standard mounting unit for connection to the vehicle.

In alternative embodiments, an event counter is beneficially provided that counts by each type of recording event in the aggregate and/or separate counter for each type of event. The counter includes or is connected to a display that displays either always or by request/actuation of a switch that optionally is only accessible to the manager for efficient determination whether the actual recording events should be viewed by, e.g., the manager.

In alternative embodiments, an audible chime is included that makes an audible sound and/or light indicator that illuminates if the vehicle/driver exceeds predetermined speed and/or for predetermined recording events such as excessive braking, and the like.

In alternative embodiments, a delay timer is included which allows the device to continue to capture video for a predetermined time after the ignition is turned off. Alternatively, the system captures still frames at regular intervals (e.g. 15 or 30 sec) to see if anyone is in and/or around the vehicle and/or captures video and/or still images when the ignition is off and a motion detector is triggered to prevent theft and/or record events in the vicinity of the vehicle.

In alternative embodiments, when forward and backward cameras are used, either two separate cameras are provided on opposite sides of a mirror, such as a rearview mirror, one camera pointing forward and another pointing backward. In other embodiments, a single structure having two cameras integrated therein, one pointing forward and the second pointing backward as described herein may be used.

According to one embodiment of the invention, the camera system is provided with a housing containing two cameras, where each camera is directed in opposite directions to capture images in the interior of a vehicle and exterior of a vehicle.

In other embodiments, camera unit 220 is fixed to one or both of housing back 207 and housing front 201 by screws or rivets. Camera unit 220 is provided with power through power cable 224 and an optional light source. In some embodiments, camera unit may be connected to an independent power source, may include its own power source and/or may share a power source with other components of system 200. According to one advantage of the present invention, camera unit 220 is portable and a self-contained unit that may be advantageously be removed from the housing to protect the camera unit, light source and/or memory from theft, tampering and/or vandalism. In other embodiments, camera unit 220 and light source 209 may be advantageously removed from the housing together to provide portability and protection of the cameras, memory, processor, recording unit and/or LED circuit board 213.

Camera unit 220 of the present invention in at least one embodiment is connected to the vehicle's ignition system to receive power. In accordance with this embodiment, the camera unit(s) will only start when ignition is turned on. In some embodiments, the camera unit(s) stops capturing audio/video after a preset (user determined) interval or immediately after ignition is turned off. In other embodiments, power to the dual-camera system is provided through a cigarette lighter cord, standard 120V or 240V power cord, USB cord, or the like. In other embodiments, the dual-camera system is hardwired into the electrical system of the vehicle.

In other embodiments, a rechargeable battery powers the system 200 and camera unit 220. Camera unit 220 optionally operates (on battery power) even when it is not cradled in the housing, in case the driver needs to capture audio/video outside the camera's normal field of vision (e.g., vehicle body damage after a collision). Alternative power mechanisms and/or battery backup mechanisms may be used, and alternative procedures for starting and stopping recording of audio and/or video may be utilized.

Additionally, camera unit 220 is provided with means for recording the output of the cameras. For example, in some embodiments unit 220 is provided with an internal hard drive, data storage device and/or other standard memory device to record the outputs of the cameras and optional microphone. In various embodiments, the outputs of the cameras and optional microphone are recorded instead of the fixed memory device and/or in addition to the fixed memory storage device, on removable media such as, for example, SD memory. In one embodiment, each of the first and second cameras are connected via 16-bit connection to a circuit board, and a memory device such as an SD card. Direct connection enables the memory to receive the video and audio signals in their original digital format, and store it as such. As will be understood, the memory device may be removed from the housing to allow the contents of the memory to be reviewed at another location. Further, the portability of the memory device protects it from theft and vandalism

An adjustment mechanism is provided that allows the angle of the housing to be changed relative to the surface to which the system 200 is mounted. Screws 222 are used to connect housing front 201 to mount 210.
